2 things to know about computer/gaming HD lenses

Known as Computer Vision Syndrome (CVS), it is one of the most common complaints in today’s workforce. Including eye strain and muscle strain across the body, staring at the computer or other types of digital screens such as laptops, tablets, and mobile phones are far from a good situation. Luckily, digital eyeglasses make strain a non-issue. Because the digital lenses in these types of eyeglasses are designed so that vision is clear no matter what part of the lens is looked through, heads and necks can remain in neutral, comfortable positions.

Digital screens also bounce other light sources into your eyes, one of the main causes of eye strain for gamers and heavy computer, laptop and tablet users. The special coating in digital eyeglasses prevent this from happening. However, older coatings actually smudged very easily, resulting in more strain. Many of these digital lenses come with a color tint to increase screen contrast as well as filter out the harsher spectrums of light that disturb your inner clock. Blocking out theses colors also allows your eye muscle to relax, and even go so far as to block all harmful light by 20%.

Though it may seem weird, when you get a pair of prescription glasses, they come with
an expiration date. This date is typically one to two years in length, but unlike food, this
date isn't just a suggestion of when you should have the prescription turned in. It is
actually a legally binding expiration. Contacts lens and glasses lens makers cannot make

Luckily, that doesn't mean your eyes are in serious trouble if you keep using glasses with
an old prescription. Unlike myths would have you believe, you will not damage your
eyes if you have to wear glasses with an expired prescription for any amount of time.
Contact lenses are different, though, as they have an expiration date that is independent of
the prescription expiration. If this date is passed, do not put in the contacts.

Even if frustrating as this can be, the date is there for a reason. Your eyes are in a
continual flux, typically rendering the prescription incorrect after the expiration period
(though this isn't always the case)

This date is great way of reminding us to have our eyes checked out at least once per
year. At this visit, eye doctors are able to make sure your sight remains clear while also
checking for autoimmune diseases.

Recommended Hi Index lenses *

What are hi-index 1.67 and 1.74 prescription lenses? Why do you have to consider lenses as an
alternative option to the standard polycarbonate lenses you offer that is already an upgrade over
plastic lenses?

Depending on your prescription, you might have the option to upgrade your lens to a hi-
index, meaning that instead of the thicker, standard lenses, you can have a lighter lens that is up
to 50 % thinner.

Hi-index 1.67 lenses are 34 % thinner than standard polycarbonate. Based on your prescription
you entered, you may want to consider this option for an additional charge.

Thinner and more expensive than 1.67 prescription lenses, the 1.74s are better for people that
have more extreme eye distortion but don't want a heavier, thicker standard lens as they are one
of the thinnest, measuring a full 50 % thinner than standard plastic lens.

As great as it may be to go with thinner lenses, a hi-index option might not fit your lifestyle.
Developed in the 1970s, polycarbonate lenses are impact resistant, sturdy and great for children,
those with active lifestyle and people that prefer rimless frames. One of its best features is a
surface that is almost as scratch resistant as glass. On top of this, these lenses are typically much
cheaper than hi-index designs.

Pupillary DIstance (PD)

WHAT IS PUPILLARY DISTANCE?

Also known as PD, pupillary distance is exactly what it sounds like - the distance between the
сenter of each pupil.
This number is one of the most important numbers needed during eyeglass fittings because it
tells the Rx glasses manufacturer where to center the lenses. If not centered to this number, the
world remains unfocused.

How do I measure PD? Manually

Find a ruler that has millimeters on it. If you don't have one, a ruler with centimeters will work
so long as you then multiply the centimeter measurement by 10 to get the length in millimeters.

Standing in front of a mirror, hold the ruler just below your eyes. After closing your left eye,
align the zero point measurement on the ruler with the center of your right pupil

Now, close your right eye and open your left eye keeping the ruler steady. Read the number that
is found at the center of your left pupil. This number is your PD.

Do this three to five times in order to ensure accuracy. If you're finding this task a bit too hard to
take on by yourself, ask a friend or family member to measure for you

Digitally

Luckily, the complicated manual option isn't the only one out there. Instead, we offer a digital measurement tool you can use in front of your own computer camera that offers a hassle free, more accurate way to get your personal PD measurement and it's quick and easy by clicking here

2 WAYS TO KNOW YOU NEED NARROW, MEDIUM OR WIDE EYEGLASSES FRAMES

Our faces are as beautifully diverse as we are. From skin color to bone structure, every tiny shift means that what works well for someone else won’t necessarily work for us. This is why there are so many eyeglass frames to choose from with so many variations in size, shape and design. While there seem to be an endless list of options, the best place to start without becoming overwhelmed is the width of the frame.

For this, there are only three possibilities:

Narrow ( 50mm or less)

Medium (51-54 mm)

Wide (55 mm or more)

If you already have a pair of glasses, you probably don’t need to reconsider this, especially if you really like the frames. In this case, simply refer to your current pair’s measurements and choose a new pair accordingly.

If this is not the case, head to a mirror with a ruler. Holding the ruler center with your eyes, measure the distance from temple to temple. If it is less than 4,5 inches, go for narrow, if it’s between 4,5 inches and 5,5 inches, wide frames are your best choice. Similarly, if you had a pair of glasses that didn’t quite fit, go larger if they squeezed your face or narrower if they kept sliding off down your nose.

HOW DO I MEASURE MY EYEGLASSES?

When it's time to pick a new set of frames, there are a few measurements to keep in mind in order to find a pair that fits correctly and comfortably.

For a great fit, you will need to measure for three things - lens width, bridge size and temple length. If you already have glasses, these should be a located along the inside of one of the arm pieces or on the nose bridge area. If the numbers aren't printed on the glasses, here's how to figure out what the measurements are

Bridge Size
Bridge size refers to the distance between the two frames where your nose comes through. Measure the distance from frame to frame or lens to lens (if you want with a frameless pair of glasses). Be sure you take this from halfway between the bootom of the glasses and the actual bridge. Expect it to between 14 and 24 mm.

Lens Width
This is how wide your lenses are in millimeters.Keep in mind that this is just the lens, not the frame. Using a ruler, measure from one edge of the lens to the other horizontally in the center of the lens. This will be between 40 and 80 mm.

Temple Length
As it sounds, temple length is the length of the temple, or arm piece. Measure from the hinge to the very back and expect it to be between 120 and 150 mm.
